The name Nicomedes points to Greek origin and he was probably a slave. 7. Goblet bearing an engraved graffito in capital letters: SIIXTVS.

The Division of Time (Display cases 7-8) With the exception of a few minor changes, the Roman calendar introduced by Julius Caesar in 46 BC, is still in use today and continues to regulate our lives. The Roman year began on January 1st and was divided into twelve months, the names and sequence of which have remained unchanged. Determining the day of a month was complicated because, unlike in present times, this was not achieved by counting from 1 to 31; instead, the Romans counted backwards from one of the three fixed points within a month: the calends (first day of the month), the nones (5th or 7th day depending on the month) (display case 8, no. 2) and the ides (13th or 15th day, again depending on the month). Every day had 24 hours. The day, from sunrise to sunset, comprised twelve hours, as did the night. Therefore, the length of an hour varied depending on the time of year and one’s geographical position. Only noon, the sixth hour (sexta hora), remained the same. In several modern languages directly derived from Latin like Italian or French, some weekdays still reflect the Roman influence such as the days named after the gods Mars (Tuesday - mardi) or Mercury (Wednesday - mercredi). In general, an hour was determined according to brightness. In order to measure time more exactly, three instruments were used: the sundial (display case 8, no. 1, drawing), which was either fixed or portable, the hourglass or the water clock (clepsydra). 1 2 25 First Floor 6 7 8

First Floor Weights and Measures The Zodiac is the celestial sphere divided into twelve equal sections. In linking astronomy with astrology, they are named after their nearest star constellations.

Two and a half feet were a pace (gradus) and one thousand double-paces (passus) were a mile (mille passus) or the equivalent of approximately 1478.5 m.
